Wheel-puller.



CHARLES H. KOHLER,

OF OAKDALE, NEW YORK.

WHEEL-FULLER.

Application led 'October 1Q. 1915.

T 0 all whom t may concern Be it known that l, @naam-:s H, Komaan, a,citizen of the United StatesY residing at Oakdale, Long. Island, in thecounty of Suffolk and State ot New York, have invented certain .new anduseful .improvements in Wheel-Fullers; and 1 do hereby declare thefollowing to be a vfull clear, and exact de; scription of the invention,such as will enable others skilled in thc art to which it appertains tomake and use the same.

This invention relates to devices for removing wheels, coupling members,and other\ similar articles provided with hubs, from their shafts; andit consists in the novel construction and combination ot the parts here?inafter fully described and claimed.

In the drawings, Figure 1 is a planv view of a'wheel puller constructedaccording to this invention. Fig. Q is a side view of thel same. Fig. 3a plan view otl one of the arms showing c. modification.

A portion of a shaft 2 is shown with a coupling member or hub 3 on it. Acrossbar 4f is provided, and is a main screw which screws in a hole inthe middle part of the crossbar. This screw has a point (S for bearingagainst the shaft, and'it has a rectangu-v lar portion T J'ir a handle.for operatingit.

Arms S are pivoted to the crossbar by pins 9, and several pivot holes 10are provided in the cross ba r so that the pins can be set at differentdistances apart. T he arms have hooked' ends 1'2 l'or engaging with thecoupling member or wheel hub. The arms have also double-eyes 1l whichstraddle the crossbar and engage with the pivot'l pins, and thesedouble-eyes are inclined inwardly and set at an angle to the mainportions ot' the arms so that the center lines of the pivot pins are,substantially at the same distance apart as the, points of the hooks.Lugs 15 project outwardly from to the crossbar, and 16 are settingscrews arranged parallel to the arms.

The screws 1G engage with holes in the against the crossbar. he

16 and the 1nlugs and bear object of using the screws wardly inclineddouble-eyes 1s to prevent the.

hooks ofthe arms from slipping when the main screw4 5 is revolved topull the conpling member or wheel .hub off the shaft.

In the modification shown in Fig. 3 each arm is formed of two parts. Theouter arm 8 is made exactly the same as hereinloefore Specification ofLetters Patent.

described but its pivot pin- 9 engages 4with a head 17 on an extensionarm 1S insteadof being pivoted to the crossbar. The extension arm 1S ispivoted to the crosebar: by a pin .19, and it has an inwardly inclineddouble-eye Q-L and an outwardly projecting lug 25 has a setting screw 26which bears against the crossbar. When the extension arms 1S are usedthe reach of the arms is greater, and the pivot 'pins 9 can be set with,l very fine adjustment by the screws QG; before the screws 1G areoperated to adjustitlie'position of the pulling hooks.

The parts are placed in position as shown in the drawings and thecoupling member or wheel hub is removed Jfrom the shaft by revolving`the main screw ropriate' direction.

What I claim is:

1. 1n a wheel or hub puller, a erossbar, a main screw engaging with theerossbar and adapted to bear against the shaft` arms provided at one endwith hooks for engaging with the hub. and havingat the other enddouble-eyes the forked portions of which straddle the crossbar and arepivoted to it. said double-eyes and ally on one side of the arms7 andsaid double-eyes having lugs which project laterally from them betweentheir forked portions and the arms and pon the other side ot' the armsfrom the hooks. and settingserews engaging with the saidl lugs andbearing on the crossbar.

'2. ,ln a wheel or hub puller, a crossbar, a main screw engaging withthe erossba and adapted to bear against the arms having heads at theirrec ends, said extension arms having at their other ends inwardlyineliiwd portions which are piv'oted to the crossbar and having alsooutwardly projecting lugs provided withsetting screws which bear againstthe crossbar, and hooked arms t'or engaging willi the hub on lliesliai't, said hoolied arms being provided at one end with inwardlyinclined portions which are pivoted to the heads of l( he extensionarms, and having also outlugs provided with setting screws which bearagainst the said heads.

In testimony whereof I have ailifxed my signature.
